Wondering what's going up on Xbox Live Arcade tomorrow? Wonder no longer - it's Defense Grid: The Awakening and Yo-Ho Kablammo.
We already knew about the former, which is a conversion of a PC tower defence game with some new levels thrown in for good measure.
The latter, meanwhile, is about ship-to-ship pirate battles and sounds as though it has a multiplayer emphasis, although there are 15 single-player challenges to fill it out.
Both games will cost 800 Microsoft Points (Ł6.80 / €9.60).
As for next Wednesday, Shacknews reports that we'll be getting Sonic & Knuckles, and that providing you've bought previous Sonic games on XBLA you will gain access to various unlockables too.
